Does anybody know what I am doing wrong when I am calling the get_portfolio function because I keep getting this error message:

E1136:Value 'self.exchange.get_portfolio' is unsubscriptable

You have a little mistake in the call:

self.exchange.get_portfolio is a function, so you first have to call it and then you can reference the entries from the returned dict.

Oh I just saw, that you also have to insert your symbol before:

qty = self.exchange.get_portfolio()[<YOUR_SYMBOL>]['currentQty']

If you don't know the symbols, you can use the keys function which lists all the keys of your dict:

port = self.exchange.get_portfolio()

port_keys = port.keys()

qty = port[port_keys[<SOME KEY NUMBER>]]['currentQty']

You should do it as follows:

qty = self.exchange.get_portfolio()

qty = qty[qty.keys()[0]]['currentQty']

or in a single row:

qty = self.exchange.get_portfolio()[self.exchange.get_portfolio().keys()[0]]['currentQty']
